Crankcase emissions device

Abstract

An improved device for separating liquid from gases and vapors passing from the crankcase of an internal combustion engine to the intake manifold thereof and allowing return of the separated liquid to the crankcase, through a conduit interconnecting the crankcase with the intake manifold, the component comprising a restricting device positioned within the conduit providing a restricted flow path in the crankcase gases and vapors.

What is claimed: 
     
       1. An improved device for separating liquid from gases and vapors passing from the crankcase of an internal combustion engine to the intake manifold thereof and allowing return of the separated liquid to the crankcase through a conduit interconnecting the crankcase with the intake manifold, the improvement comprising a restricting means providing a restricted flow path for the crankcase gases and vapors and a surface upstream of said restricted flow path for allowing separated liquid to collect thereon for return to the crankcase, said restricting means including a ring-like member adapted to be held in mating relationship with and within the conduit, said ring-like member having a port to allow fluid flow therethrough, a tube-like member extending from one side of said ring-like member and providing a flow passage with said port, and baffle means associated with said tube-like member generally to block direct flow into the flow passage of said tube-like member, yet allow access to the flow passage for flow through said tube-like member such that liquid associated with the crankcase gases and vapors will tend to collect at said device for return to the crankcase. 
     
     
       2. A device, according to claim 1, wherein said baffle means comprises a flange extending across the flow passage and a tube-like member spacing said flange slightly from said tube-like member to provide access to said flow passage. 
     
     
       3. A device, according to claim 2, which further includes baffle means at the port of said ring-like member, generally adjacent its outlet end.
